Highway Driving Assist

Display and control

The operational status of the Highway Driving Assist (HDA) system in your Kia K4 is clearly visible within the "Driving Assist" view on the instrument cluster. For a deeper understanding of how these visual cues are organized, please refer to the "LCD display modes" section of your owner’s manual.

The Highway Driving Assist status is communicated to the driver through the following indicators on the Kia K4 instrument cluster:

1. Highway Driving Assist Indicator: Displays whether a vehicle is detected ahead and shows the currently selected following distance level.

   • Green: The system is actively operating.

   • Gray: The system is in standby mode, waiting for proper conditions.

   • White blinking: Indicates that the accelerator pedal is engaged by the driver, overriding the system.

   • Unlit: The function is completely OFF.

2. Set Speed: Indicates the target cruising speed defined by the driver.

3. Vehicle Detection and Headway: Visual confirmation of a lead vehicle and the distance gap settings.

4. Lane Detection Status: Confirms whether the system has successfully identified lane markings.

5. Lane Following Assist (LFA) Indicator: Shows the active state of the lane-centering feature.

TIP

Turning on Highway Driving Assist

To ensure optimal performance in your Kia K4, Highway Driving Assist functions only when specific criteria are met:

• Press the "Drive Assist" button to activate Highway Driving Assist while driving on supported controlled-access highways.

• If you are entering a highway main road while Smart Cruise Control is active, please be aware that Highway Driving Assist will not engage if the Lane Following Assist (LFA) feature has been turned OFF.

Restarting after stopping

Use the steering wheel switch or accelerator pedal to resume movement.

When Highway Driving Assist is active, the Kia K4 will automatically bring the vehicle to a full stop if the car ahead stops. If the lead vehicle resumes motion within 30 seconds, your Kia K4 will automatically start following it. If the stop lasts longer than 30 seconds, a notification appears on the instrument cluster. To resume driving, either press the accelerator pedal or toggle the (+), (-), or (RES) switches on the steering wheel.

Hands-off warning

Driver hands-off warning indicator.

Keep hands on steering wheel

To ensure safe operation of your Kia K4, the system continuously monitors steering input. If you remove your hands from the steering wheel for several seconds, the Kia K4 will provide a multi-stage warning to regain your attention:

• First stage: An informative warning message appears on the instrument cluster advising you to place your hands back on the wheel.

• Second stage: The warning message intensifies, displaying a red steering wheel icon accompanied by a continuous audible chime.

Highway Driving Assist deactivated

If you fail to return your hands to the steering wheel after the multi-stage warning sequence, the Highway Driving Assist (HDA) system in your Kia K4 will automatically cancel to prevent unsafe operation.

Driving the speed limit

Driver’s grasp not detected. Driving speed will be limited.

Once the hands-off warning leads to the cancellation of Highway Driving Assist, the Kia K4 will initiate a speed-limiting function for your protection. During this phase, a persistent warning message is displayed on the instrument cluster, and an audible alarm sounds continuously to urge the driver to resume control.

Driving to one side within lane:

When driving your Kia K4 at speeds above 40 mph (60 km/h), if another vehicle is detected in close proximity within an adjacent lane, the system will proactively provide subtle steering control to bias the vehicle toward the opposite side of the lane, enhancing lateral safety. Note that if vehicles are positioned closely on both sides of your Kia K4 simultaneously, this specific evasive steering assistance will be suppressed.

Highway Driving Assist standby

If the Smart Cruise Control (SCC) component of the Kia K4 is temporarily interrupted while Highway Driving Assist is active, the system enters a standby mode. In this state, the Lane Following Assist (LFA) feature will continue to operate independently to help keep the vehicle centered.

NOTE

Highway Lane Change Assist:

Display and control

The operational status of the Highway Lane Change Assist (HLCA) system is conveniently displayed directly on the instrument cluster of your Kia K4. For a comprehensive overview of how these status updates are presented, please refer to the "LCD display modes" section of your owner's manual.

The status of the Highway Lane Change Assist in your Kia K4 is categorized as follows:

1. Highway Lane Change Assist Indicator: Provides status icons on the Kia K4 dashboard:

   • Green (): System is ready for operation.
   • Green blinking (): System is currently performing a lane change maneuver.
   • Gray (): System is in standby mode.
   • White blinking (): Operation has been canceled; this alert displays briefly post-cancellation.

2. Lane Line Display: The lane markings on your Kia K4 display mirror the color-coding of the HLCA indicator. When the system is in Standby, it will also visually represent the availability of lane detection.

3. Green Arrow and Lane Shade: A visual green arrow and lane highlighting appear after the system initiates the maneuver and remain until the lane change in your Kia K4 is successfully completed.

4. Status Messages:

   • An informational message appears if the HLCA cannot engage when you trigger the turn signal lever.
   • A notification appears if the HLCA is interrupted while currently operating.

You can enable or disable the Highway Lane Change Assist feature in your Kia K4 by using the "Driving Assist" or "Lane Driving Assist" button on your steering wheel.

Turning ON Highway Lane Change Assist

Press the OK button on the steering wheel to enable Lane Change Assist.

The Highway Lane Change Assist feature in your Kia K4 is fully ready to operate when the function is enabled and the following environmental and system conditions are met:

• Highway Driving Assist is currently active and managing vehicle speed/lane position.
• Lane Following Assist is fully operational and detecting lane markings.
• The vehicle is powered ON and has detected other vehicles in the adjacent lanes (detected more than once).
• Driving speed is maintained above 20 mph (30 km/h).
• When driving between 20-40 mph (30-60 km/h), the Kia K4 successfully recognizes surrounding traffic in the left and right adjacent lanes, and the system confirms there is no risk of collision during the lane change.

• The instrument cluster does not display the hands-off warning for your Kia K4.

• Hazard lights are currently OFF.
